Getting Started#
PythonRustNode.jsROS2DevOps
Initialize a workspace:<br>pixi init hello-world<br>cd hello-world
Add dependencies into the default environment:<br>pixi add cowpy python
Create your script:<br>hello.pyfrom cowpy.cow import Cowacter
message = Cowacter().milk("Hello Pixi fans!")<br>print(message)
Add a task:<br>pixi task add start python hello.py
Run the task:<br>pixi run start
✨ Pixi task (start): python hello.py
\ ^__^<br>\ (oo)\_______<br>(__)\ )\/\<br>||----w |<br>|| ||
Enter the shell into the environment:<br>pixi shell<br>python hello.py<br>exit
More details on how to use Pixi with Python can be found in the Python tutorial.
Initialize a workspace:<br>pixi init pixi-rust<br>cd pixi-rust
Add dependencies:<br>pixi add rust
Create your workspace:<br>pixi run cargo init
Add a task:<br>pixi task add start cargo run
Run the task:<br>pixi run start
✨ Pixi task (start): cargo run<br>Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.02s<br>Running `target/debug/pixi-rust`<br>Hello, world!
This is more of an example to show off how easy it is to use Pixi with Rust.<br>Not a recommended way to build Rust projects.<br>More details on how to use Pixi with Rust can be found in the Rust tutorial.
Initialize a workspace:<br>pixi init pixi-node<br>cd pixi-node
Add dependencies:<br>pixi add nodejs
Create your script:<br>hello.jsconsole.log("Hello Pixi fans!");
Add a task:<br>pixi task add start "node hello.js"
Run the task:<br>pixi run start
✨ Pixi task (start): node hello.js<br>Hello Pixi fans!
Initialize a workspace:<br>pixi init pixi-ros2 -c https://prefix.dev/conda-forge -c "https://prefix.dev/robostack-humble"<br>cd pixi-ros2
Add dependencies:<br>pixi add ros-humble-desktop
This might take a minute<br>Depending on your internet connection, this will take a while to install, as it will download the entire ROS2 desktop package.
Start Rviz<br>pixi run rviz2
More details on how to use Pixi with ROS2 can be found in the ROS2 tutorial.
Install all your favorite tools with a single command:<br>pixi global install terraform ansible k9s make
Use them everywhere:<br>ansible --version<br>terraform --version<br>k9s version<br>make --version
